Carlton House, on the Saskatchewan River (about lat. 53°), to the Rocky
Mountains, Drummond !—A stout showy species, with ample thickish veiny
leaves (4—6 inches long and 1—2 wide, the teeth triangular and mucronafe or
subulate-pointed), and heads fully as large as those of A. spectabilis, to
which it bears considerable resemblance. Involucre and peduncles viscid
with a minute glandular pubescence. Rays large, blue. Appendages of the
style triangular-lanceolate. Bristles of the pappus slightly rigid, similar,
and scarcely, if at all thickened upwards.
7. A . spectabilis (Ait.): stem strict, puberulent-scabrous, glandular-pubescent
and corymbose at the summit; leaves oblong-lanceolate, scabrous,
sessile, entire; the lower ones oblong, remotely appressed-serrate, tapering
into a short margined petiole; branches ot the corymb usually short and
rigid, bearing 1-3 heads; involucre hemispherical-campanulate, as long as
the disk ; the scales very numerous, somewhat equal in length, linear-oblong
and slightly spatulate, glandular-puberulent, somewhat ciliate, with conspicuous
herbaceous squarrose-spreading (rather obtuse) tips; rays numerous
(20 or more); achenia linear, slightly pubescent.—Ait. Kcw. (ed. 1 ) 3. p.

Dry sandy soil and pine barrens, Massachusetts (New Bedford, Mr. T. A.
Green !) and New Jersey! to Florida ! and Kentucky ! Sept.-Nov._Rhizoma
slender, creeping. Stem 1-2 feet high. Leaves 2-4 inches long (the
u pi>er ones smaller), half an inch to an inch in width, of a firm texture,
acute or obtuse, mucronulate, sometimes obscurely 3-nerved. Branches of
the corymb or peduncles with a few small leaves or bracts (the uppermost
approximate to the head), usually short and rigid. Heads showy (larger
than in A. A melius); the scales of the involucre imbricated in several series;
the exterior loose, clothed more or less with a glandular-scabrous pubescence
similar to that of the branches. Rays very long, lanceolate, blue or violet.
Appendages of the style lanceolate-subulate.—We have met with no authentic
specimen of Mr. Nuttall’s var. bellidifolius. Perhaps he had a
form of the closely allied A. gracilis in view; since the latter is common
in the pine barrens of New Jersey, while he only mentions it as a Western
plant.
8. A. gracilis (Nutt.): stems several from the same often surculose cau-
dex, slender, slightly pubescent, corymbose at the summit; leaves somewhat
scabrous, remotely and obscurely crenulate-serrate ; the radical ones oblong or
spatulate, on slender naked petioles; the cauline oblanceolate or narrowly
oblong, often narrowed at the base, slightly clasping; heads several, in a
spreading corymb; involucre obconical, as long as the disk; the scarcely
pubescent scales imbricated in several series, whitish and coriaceous, with
herbaceous (obtuse or slightly pointed) spreading tips ; the exterior successively
shorter; rays about 1 2 ; achenia cuneiform-oblong, moderately compressed,
minutely hairy.—Nutt. ! gen. 2. p. 158.
Prairies of Kentucky & Tennessee, Nuttall! Pine barrens of New Jersey!
common. Sept.—Caudex usually tuberous, producing runners and offsets.
Stems about a foot high, not scabrous or glandular, leafy, either simple and
bearing 5 to 9 heads in a terminal corymb (the central head almost sessile,
the lateral on slender spreading or divaricate peduncles); or with corymbose
flowering branches, each bearing 3 to 7 heads, all but the lateral or external
on very short pedicels. Leaves 1 to about 2 inches long, nearly coriaceous,
opaque, glabrous. Involucre almost exactly like Sericocarpus conyzoides !
and about the same size; the exterior scales subspatulate-oblong or linear-
oblong, somewhat ciliate ; the innermost linear, membranaceous. Heads
about 30-flowered. Rays violet; the ligules exserted about the length of the
involucre. Achenia rather short, impressed-striate, clothed with short sparse
hairs.—Mr. Nuttall has correctly remarked the alliance of this plant to A.
spectabilis on the one hand (some forms of which it greatly resembles), and
to Sericocarpus conyzoides on the other: it almost .connects the latter genus
with Aster.
9. A. surculosus (Michx.) : stems several from the same surculose caudex,
slender, simple, minutely pubes.cent above; leaves lanceolate, elongated,
acute, glabrous, the margin scabrous, entire or with a' few slight subulate
teeth ; the lowermost tapering into a margined somewhat sheathing petiole ;
the upper ones linear, partly sheathing or clasping at the base; heads 3-5 in
a simple corymb (sometimes solitary); involucre turbinate-hemispherical,
nearly as long as the disk; the scales numerous, somewhat equal in length,
pubescent, with spreading herbaceous mostly mucronulate tips; the outermost
lanceolate and chiefly foliaceous; rays numerous; achenia linear, almost
glabrous.—Mich x .fi. 1 . p. 1 12 ; Nutt.! gen. 2. p. 157; Nees, Ast.

swamps in Tennessee, N. Carolina ! and Virginia, Nuttall. Wilmington, N.
Carolina, Nuttall! Mr. Curtis ! Southern States, Mr. Croom ! Sept.__Rhizoma
creeping. Stems somewhat angled, 6-18 inches high; the summit, peduncles
&c. pubescent but not glandular. Leaves rather scattered, rigid, opaque
(the lower obscurely 3-nerved), smooth and shining; the lower 4-6 inches
long, lanceolate or spatulate-lanceolate ; the cauline successively reduced to
one or two inches in length, often narrowly lanceolate-linear ; the uppermost
confluent with the scales of the involucre. Heads as large as in A. spectabilis
; the rays long, linear, violet. Exterior scales of the involucre loose,
lanceolate ; the others linear-spatulafe or narrowly cuneiform, rigid, white at
the base, the tips herbaceous, mucronulate ; the innermost nearly membranaceous.
Achenia striate, slender, somewhat compressed__The dwarfish
state of this species (which we believe to be Michaux’s) approaches A. spectabilis,
while the most slender forms considerably resemble the very different
A. paludosus.
10. A. paludosus (Ait.): stem slightly puberulent or scabrous; leaves
linear, entire, acute, rigid, partly clasping, with the margins scabrous, often
fringed with bristly hairs near the base ; heads few, racemose, or terminating
the mostly simple axillary and somewhat racemose branches; involucre hemispherical,
nearly the length of the disk, mostly bracteolate ; the scales numerous,
somewhat equal in length, partly foliaceous, lanceolate or spatulate-
linear, mucronate, somewhat squarrose ; rays numerous; achenia linear-oblong,
nearly glabrous.—Ait. Kew. {ed. 1 ) 3. p. 201 ; Pursh, fi. 1. p. 547 ;
